Ions

This Chemistry lesson is titled Bonding in Polyatomic Ions and Compounds and will give a detailed explanation of the topic.

Part 9 of the acid base series for Mr. Newton's acid base equilibria series. This lesson covers some weak base calculations as well as how to figure out patterns and correlations between weak base situation and other salts containing the same ions.

This Chemistry lesson is titled Huge Misconception Protons Electrons Atoms and Ion with Molar Mass and will give a detailed explanation of the topic.

This chemistry lesson is titled Writing Formulas with Polyatomic Ions and will give a detailed explanation of the topic.

In this part 9 of the solution equilibrium series we analyze the solubility product constant in light of being added to a solution of a common ion, plus we learn how to use the reaction quotient (Q) to predict whether or not a solution will form a precipitate.

Formation of ions.

This Chemistry lesson is titled Biggest Mistakes in Chemistry Polyatomic Ions and will give a detailed explanation of the topic.

This video discusses and explains the weak acidity of carboxylic acids. It looks at methanoic to hexanoic acids and also includes trichloroethanoic and benzoic acids. The concentration of hydrogen ions, pH and percentage dissociation are used in the discussions, together with electron-withdrawing and electron-donating properties of groups attached to the carboxyl group.

Many practice problems for how to calculate and determine oxidation numbers, often referred to as oxidation states. To figure out oxidation numbers for elements in a compound, we have to look on the periodic table and consult a list of rules. For neutral compounds, the oxidation numbers add up to zero. For polyatomic ions, the oxidation numbers add up to charge of the ion.
